My invention relates to a radiator for house heating, and more particularly to the type employing ns for the conduction and radiation i of heat.

The principal object of my invention isto cast a radiator in one piece and provide means whereby radiator iins may be easily assembled and maintained in uniform alignment.

Another object is to provide fins of either single -plate or corrugated sectional form Which are complete these operations, which increased the manufacturing cost. ,With my improved type of radiator and 1in construction,` one casting is made of the body with the included leg portions or fia end fittings cast integrally therewith, and the ns are adapted to be assembled by placing same over the top ofthe body portion. The iins are maintained in a set position by means of positioning grooves or slots. The entire assembly is then dipped in a galvanizing bath whichseals the fins on the body portion and provides a good metallic f contact between the ns and the radiator body.

These and other features will appear in the following description and drawing, in which:

' Figure 1 shows an elevational view,'with part in section, of a one piece radiator assembly having fins thereon;

Fig. 2 isa vertical section taken on the line 2 2 of Fig. 1;

Fig. 3 is a perspective detail of a single plate 1in having flanged edges;

Fig. 4 is a vertical section of a modied form of radiator showing a plurality of central tubular or body portions cast integrally with the end members;

vFig. 5 is a side elevational View, with a part broken away, of a one piece cast Wall radiator assembly having fins thereon.

The radiator in general, shown in Fig. l, com? from the lower end .of leg 12 through the main body structure to the lower end of the other leg 14. Threaded openings 18 communicating with the passages in each of the legs are adapted to receive suitable pipe ttings or plugs. The upper edge 20 of the body portion khas evenly spaced 1in positioning slots 22 cut into the surface to receive iins 24.

The ns 24 are stamped from sheet metal and have a slotted lower portion 26 shaped to correspond with the shape of the body portion 10.v

In Fig. 2, I show the body, for example, as wedge shaped, and the iin in Fig. 3 with a Wedge shaped slot 26 adapted to fit over the said body portion. Inwardly disposed iianges 28 are formed at the edges of the slotted portion which provide a large contacting surface area when in engagement with the body portion 10. Flanges l30 are formed on the sides of the fins to provide a flush side surface when assembled, and individual pockets for the heated air to pass through.

VThis type of fin is assembled by slipping the slotted .end 26 over the body portion 10 of the radiator and forcing same downward until the flat portions 32 at the apex of each wedge shaped slot 26 engage the slots 22 in the body'lO. The flanges 28 converge slightly toward each other and provide a substantial grip on the sides of the body portions after assembling. When the ns are all assembled, they aremaintained in a fixed position and properly spaced relation by -means of the gripping action of the flanges 28 and positioning slots 22.

After the` assembly is completed, the entire unit is dipped in a galvanizing bathwhich coats therradiator with a galvanized iinish and seals the fins in their set position on the body. portions as well as providing a good metallic contact.

In Fig. 4, I have shown a modified form of one piece cast radiator in which a double body, or two tube body portion 34 is cast integrally with end leg members 36. Fins 38 are provided with two slotted openings 40, and are adapted to straddle the body 34 when assembling. Grooves 42 in each of the two tubular portions 34, position the fins in the same manner as the slots 22 previously described. More than two body portions may be provided if desired.

Fig. 5 illustrates a wall type radiator which is similar to the form previously described, with the exception of the leg portions. Short stub portions 44, 46 project below each end portion, and are provided with threaded openings 48 for suitable pipe fittings. A

Various changes may be made in the strucsoi ture here shown and described as forming .this invention any such changes still being within the scope of the invention here claimed, if the principles of construction and the results above described are substantially preserved.

Having described my invention, I claim:

1. In a radiator of the character described, a wedge shaped cast hollow body portion having legs cast integrally therewith, stamped ns having a wedge shaped open lower portion adapted to engage the surface of the body portion,and slots in the upper edge of said bodyportion adapted to have each n inserted within saine and to retain said ns in their set positions.
